19 Claims.

This invention relates generally to brush making machines and inparticular to a brush making machine in which a series of relatedoperations are successively performed on a brush block to complete abrush. This application is a, continuation of application Serial No.480,353, flied March 24, 1943, now abandoned.

The prior art machines for making brushes in a series of operationssuccessively performed on a brush block by related operating units, suchfor example as machines for making toothbrushes and the like, includerelatively complicated and bulky mechanism for moving a brush block fromone operating unit to a next related operating unit and for successivelymoving a brush block, in a predetermined path, to a plurality ofoperating positions relative to the same operating unit. As a result ofthis complicated mechanism the initial cost of the machine, as well asthe cost of servicing and attention required to maintain an efllcientoperation of the machine, is greatly increased. Also the complexity ofthese mechanisms appreciably reduces their production as well as theirflexibility for application to brushes having different bristlearrangements or patterns thereon.

Further, in the prior-art machines of this type which use a straightanchor for retaining a bristle tuft in the brush block, considerabledifllculty has been encountered in positively providing for theinsertion of the anchor lengthwise into the brush block. The mechanismfor inserting the anchor in the brush block usually consists of a pairof jaws having a groove in each closing portion for supporting andguiding the straight anchor at its ends while it is driven lengthwisefrom the jaws or guides into the brush block by a driving rod acting ona longitudinal side of the anchor.. If the anchor is initially tilted ormisaligned relative to a plane which is substantially normal to theinner faces of the closing portions of the jaws or guides, thismisalignment is generally increased or aggravated rather than correctedwhen the driving rod engages and pushes the anchor, so that the anchoris oftentimes driven into the brush block when it is in a substantiallyIt is apparent of course that when driven in this position the anchorfails entirely in its function to retain or anchor a correspondingbristle tuft in the brush block.

It is an object of this invention, therefore, to provide an improvedbrush making machine.

' It is a further object of this invention to provide a brush makingmachine having a continuously rotating rotary table for carrying thebrush blocks, in which a brush block is adjustably moved relative to thetable and to an operating unit, during rotation of the table, tocontinuously position thebrush block as it passes an operating unit sothat like operations are performed on the brush block along apredetermined path.

Yet a further object of this invention is to provide a brush makingmachine having a rotary table in which a selected positioning of thebrush block relative to the table and to an operating unit isaccomplished during the continuous rotation of the table in a singledirection.

Another object of this invention is to provide a brush making machinehaving a rotary table for carrying a brush block. in which means areprovided to successively move the brush block from one operating unit toa next related operating unit, and to selectively position the brushblock to have a series of like operations performed thereon along apredetermined pattern, all while the table is intermittently butcontinuously rotated in a. single direction.

A still further object of this invention is to provide in a brush makingmachine means providing for an anchor of straight form being alwaysdriven substantially lengthwise into a brush block.

Another object of this invention is to provide, in a, machine for makingbrushes having straight anchoring means for holding a bristle tufttherein, means for locating the anchor in the anchor inserting meanssuch that the anchor is always inserted in a lengthwise position withinthe brush block.

A feature of this invention is found in the provision of a brush makingmachine havinga rotary table, in which a brush block holder is movablysupported on the table and adjustable during rotation of the table bystationary means adjacent the table to define a predetermined path oftravel of the brush block relative to an operating unit.

Yet another feature of this invention is found in the provision of abrush making machine, in which an anchor of straight form is initiallypositioned in anchor inserting means by combination anchor forming andcarryi g means, such that it is always located in a plane substantiallynormal to the inner faces of the closing portions of the jaws prior tothe engagement of the anchor with an anchor driving rod. Furtherobjects, features, and advantages of this invention will become apparentfrom the following description when taken in connection with theaccompanying drawings, in which:

Fig. 9 is a detailed fragmentary elevational view partly in sectionshowing the assembly arrangement of a tuft packing and picker mechanism,tuft and anchor inserting jaws, and a tumbler unit, these mechanismsbeing shown in relation to a brush handl or block located on therotatable machine table.

In the practice of this invention there is provided a simple andefliciently operated brush making machine which in a continuousautomatic operation requiring only the feeding of brush blocks orhandles to the machine and the removal therefrom of the finished brushby an operator, acts otherwise to automatically adjust a handle carriedon a rotary table for successive operations thereon by an operatingunit, to drill spaced holes in tWo rows in the handle, to separatesubstantially measured tufts of bristles from a bristle holdingmagazine, insert the tufts within the rows of holes in the handle,secure the tufts within the handle by means of a wedging or anchoringpin of straight form, uniformly comb the bristles and then trim thebristles to the same height. All of the operating units foraccomplishing the above defined operations are arranged about a rotarytable on which the brush blocks are carried in an angularly spacedrelation. The brush is completed during substantially one revolution ofthe table so that the finished brush comes off the table atapproximately th same place that the brush block was originallypositioned upon the table,

Adjustable holders for the brush blocks arearranged substantiallytangentially of the rotary table and are pivoted near one end forsliding pivotal movement on the table within defined limits. The pivotalmovement of a brush block in one direction is accomplished by sprinmeans acting on the brush block holder and movement in an oppositedirection by stationary means having a follower portion engageable witha corresponding cam portion on the brush block holder. The followerportion is substantially in a ertical plane which includes the operatingportion of an operating unit and acts on the cam portion, as the brushblock is moved past the operating portion by the rotating table, tocontinuously position the brush block relative to the table andoperating portion to provide for a series of like operations beingperformed on the brush block along a predetermined path. Thus forexample in toothbrushes, the rows of bristles may be arranged inparallel alignment longitudinally over the brush portion of the brush,or such rows of bristles may be straight but inclined at an anglerelative to each other. It is readily apparent, of course, that with thebrush block in a fixed position on a rotating table, the rows ofbristles would be of a substantially arcuate shape because of thearcuate path defined by the brush block as it travels by an operatingunit on the rotating table. In other words, the arcuate path will be ofa shape corresponding substantially to the peripheral contour of therotating table. To accomplish an operation of the operating units in alinear path on the brush block'adjustable means are provided forcontinuously positioning the brush block, as it passes an operatingunit, relative to the rotating table and operating unit. The adjustablemeans are adapted to move the brush block for operations thereon inparallel straight lines, or in straight lines inclined relative to eachother.

As previously mentioned, considerable difficulty is encountered in brushmaking machines using straight anchors, in positively assuring theinsertion of the anchors lengthwise into the brush block. In thisinvention anchor carrying fingers, which are also included in the anchorforming mechanism of the machine, are adapted for co operative actionwith a pair of jaws for inserting the anchor in a brush block, so as toposition the anchor lengthwise between the closing portions of theanchor inserting jaws and in a plane substantially normal to suchclosing portions, with the anchor ends in a position to be positivelylocated within guiding grooves in the jaws. The anchor is retained inthis position by the anchor carrying means until the jaws are closed onthe anchor. The anchor carrying means are then released or retractedfrom a carrying or holding position relative to the anchor to permitengagement of the anchor with an anchor driving rod for anchor insertingpurposes.

The machine is illustrated in the drawings for making a brush having apair of straight rows of bristles extended longitudinally of the brush,but inclined relative to each other, this arrangement of the rows beingcommon in toothbrushes. It is to be understood, of course, that themachine is not limited alone to the making of toothbrushes and may beused in the making of brushes having straight parallel rows, or a singlestraight row, such as an eyebrow brush, or for making a brush havin oneor more rows of shapes other than linear.

As shown in Fig. l of the drawings, a brush block or unworked handle 20is positioned in a holder 2| carried on a rotary table 22 which isrotated in a counterclockwise direction as indicated by the arrow inFig. 1. The holders 2| are angularly spaced in a circle about the tableand near the outer periphery thereof. A brush block 20 is positionedwithin a corresponding holder when such holder is in the positionindicated in Fig. 1 at A, and is arranged within the holder so as toextend longitudinally in a direction which is substantially tangentialto the table 22. When the brush block is in the position indicated at Alocking means 23, operatively associated with a each holder 2! forreleasably locking a block in a holder. is automatically held in areleased position by a stationary cam 24, carried on the table axismeans 6| to permit thefree removal of a finished brush and the insertionof'a new block within the holder. The locking means 25 is held in areleased position for a movement of the block from its position at A toa position indicated at B. On leaving the position B the block is lockedin a fixed position within a corresponding holder 2| so as to be firmlyheld while the ineifective to release stationary blades 8 operativelyassociated with various operations providing for a completed' brush areperformed ,on the block. At the position C the block is operated on by adrill unit, indicated generally as 26, which drills one row of holes 26in the brush block for receiving bristle tufts. As illustrated, themachine is adapted to provide a brush having two rows of bristles, witheach row being comprised of six tufts. Since each tuft requires acorresponding drill hole, means are provided to rotate the table suchthat the brush block is positioned in six positions relative to thedrill unit 26 to provide for the drilling of the six holes.

When the brush and holder assembly are rotated to a position shown atD,'the brush is operated on by a tuft inserting and anchor wedging unit21, which inserts tufts in the row of holes made by the drill 26. Asseen in Fig. 9 this unit includes an anchor driving means 29 and a tuftand anchor carrying jaw means 29 adapted to have a bristle tuftpresented thereto by a picker member 3|. An anchor is carried to the jawmeans 29 by a combination anchor form ing and carrying means 32 (Fig.6). The tuft inserting and anchor wedging unit 27 operates to insert andsecure a tuft within the corresponding holes in the row so that thetable is also rotated to six operating positions relative to this unit.A brush block 20 is positioned in an operating position relative to thedrill 26 concurrently with the positioning of a drilled brush block atthe tuft inserting unit 21. Rotation of the tables at six operatingpositions thus provides for the concurrent operations of drilling andtuft inserting in corresponding brush blocks.

After the bristles are secured in the row 25 the brush block is moved toa position at E where it is operated on by a second drill unit 33,similar to the drill 26, for drilling a second row of holes 90 in thebrush block. On completion of this second drilling operation the brushblock is moved to a position F to be operated on by a second tuftinserting an anchor wedging unit 34, similar to the unit 21, whichinserts and anchors the tufts in the row of holes 30, It is to beunderstood, of course, that both of the drilling operations andthe tuftinserting and anchor wedging operations are performed simultaneously,but on different brush blocks, so that the making'of the brush is acontinuous operation. On completion of the drillin and tuft insertingoperations the brush block is moved substantially to a position G wherethe bristles in the rows 25 and 30 are combed by a combing mechanismindicated generally as 36. The comb 36 includes a pivoted combing plate31 which is pivotally reciprocated in an arc transversely of the bristletufts in the rows 25 and 30. When the bristles are properly combed andcleaned the brush block is moved to the position indicated at H, whereit is operated on by a trimmer mechanism 38. The cam portion 24a,radially spaced from a block 20 at the position H serves merely to guidethe follower portion 4| of the locking means 23 into an engagingposition with the cam portion 24b and is a reciprocating blade R, withthe row of bristles being passed in a direction longitudinally betweenthe stationary blades. As the block leaves the trimmer mechanism 98 thefollower portion 4| of the locking means 23 is engaged by the stationarycam portion 24b to release the completed brush for removal at theposition A. It is seen, therefore, that the locking means 23 is retainedin a released position substantially between the positions A and B andfurther that all of the operations on the brush block 29 to produce acompleted brush are accomplished in something less than one completerevolution of the rotary table 22. l

The locking means 22, shown in detail in Fig. 4, includes a locking bar39 movably supported for movement in a direction substantially radiallyof the table 22 and transversely of a corresponding block holder 2|. Therod 39 is of a substantially L-shape with the short leg or followerportion 4| extended upwardly, as viewed in Fig. 4, for engaging the camor lip portion 42 on the cam means 24. The long leg of the rod 39 ispivotally connected at portions 43 and 44 with a corresponding linkmember 46 and 41, which link members in turn are pivotally connectedwith the table 22. This pivotal connection of the looking rod 99 withthe table 22 permits movement of the rod both transversely and upwardlyrelative to the block holder 2|. The free end oi the locking rod 39extends at least partially over a cavity 46 in the holder 2| forreceiving a brush block 29, With the brush block 20 in the cavity 48,its top surface projects slightly above the top level or the holder 2|for frictional engagement with the locking rod 39. The rod 39 is movedinto a locking position by a spring 49 connected at one end to thepivotal connection of the rod portion 43 and at its opposite end to thepivotal connection of the leg 41 with the table 22. Movement of the rod39 out of a locking position relative to the holder 20 is accomplishedby the cam means 24 in response to the rotation of the table 22 relativeto the cam means. The hinged or pivoted connection of the rod 39 withthe table 22 provides for a positive locking of the block 20 in acorresponding holder 2| regardless of any slight differences in thethickness of the brush handles being worked on. This pivoted connectionalso prevents any loose bristles which might fall on the table 22 frominterfering with a free movement of the locking bar 39.

The cam means 24 is fixed on a stationary axis means 5| (Fig. 1) uponwhich the table 22 is freely rotatable. The table 22 includes twosections 52 and 53, which are suitably connected for concurrentrotation, with the complete table assembly 22 being slidably supportedfor rotation on a base portion (not shown) for the machine, which islocated below the table section 53. In order to rotate the block 2| fromone operating unit to a next related operating unit and successivelyrelative to the same operating unit the section 52 is formed on itsperipheral surface with angularly spaced ratchet or rack portions 54,and

the periphery of section 53 with angularly spaced notches 56. Althoughthe sections 52 and 53 are illustrated as being separate it is to beunderstood that these two parts can be integrally constructed. Eachratchet portion has a series or set of six teeth. As previouslymentioned the brush with which this invention is illustrated iscomprised of the locking means 22. The

or hole in the brush being made.

two rows of bristles 25 and 20' with each row including six tufts. Thereis thus a tooth in each ratchet portion -54 which corresponds to a tuftThe teeth in each tooth set or ratchet portion 54, on the section 52,-are engageable with a pawl or dog member 51 pivotally carried on a crankarm 56 having one end pivotally supported on the table axis means Theopposite end of the crank arm 58 is pivotally connected to one end of aconnecting for the table 22, ten of which are indicated in Fig. 1. Thesenotches are selectively engageable with a pawl or dog 62 pivoted on arocker arm 63. which is pivotally supported at one end on the axis means5| and pivotally connected at its 0D- posite end with a connecting rod64 adapted to drive the arm 63 in a predetermined sequence relative tothe arm 56.

In the operation of the machine the rotation of the table 22corresponding to one tooth space in a tooth set 54 advances the table ina counterclockwise direction a distance adapted-to provide for thedrilling of another hole in the brush block or the insertion of anothertuft in a corresponding hole, it being previously explained that the operation of the machine is continuous with the drilling and insertingoperations performed conrod 6| which is'connected to a suitable drivingcurrently on different brush blocks. The pawl the pawl 51. On the sixthstroke of the pawl 51 and the corresponding sixth stroke of the pawl 62the pawl 52 moves into engagement with the notch 56 corresponding toeach brush station and advances the table to the next brush station. Itis seen, therefore, that the pawl 51 moves the table only a fractionalpart of the distance which the table is moved by the pawl 62.

For the large table movement accomplished by the pawl 62 some diflicultymight be encountered in stopping the table 22 at a position such thatthe teeth 54 are correctly located with reference to a position of thebrush block 20 providing for the performance of a series of likeoperations thereon. To assist in the stopping of the table at thedesired position, brake linings (not shown) may be provided between thetable 22 and the base portion upon which it is supported.

As explained above, with the holders 2| in a fixed position on therotary table 22, the brush blocks 20 will be moved in an arcuate pathrelative to an operating unit, which path would determine the shape ofthe bristle row in the brush. In order to provide for the bristles beingarranged in a pair of straight rows inclined relative to each other,while the block 2|! is continuously rotated on the table 22 tosuccessive operating positions, a holder 2| is adjustably movable forsliding movement relative to the table by means now to be described.

Each holder 2| is of a substantially rectangular form and is extendedlongitudinally in a direction substantially tangential to the peripheryof the table 22. The cavity 48 in each holder 2| extends longitudinallyof a, corresponding holder 2| s to in turn provide for the positioningof the handle 20 being worked on in a direction substantially tangentialto the periphery of the. table 22 (Figs.

2 and 3) Each holder at its end 63, at which the handle portion of theblock 2| is arranged, is pivoted on a pin 64 carried on the table 22.The pivotal movement of the opposite end" of the holder 2| is defined bya Pin 66 on the table 22 which is slidably received in an elongatedopen,- ing or cavity 61 formed in the holder. The holder end 64 is movedin a direction toward the periphery of the table 22 by springs 65arranged-in compression between the holders 2| 'and stop portions ID onthe table 22 as is illustrated only for the brush block 2| at theposition C in Fig. 1. A pivotal movement of the holder end 64 inmopposite direction, or inwardly toward the center of the table 22, isaccomplished by a stationary follower means 58, carried on the machineframe adjacent the table 22, which engages a corresponding cam surfaceor portion 56 formed on the holder 2| adjacent the holder end 64.

Referring to Figs. 3, 4, and 5, the adjustable stationary means 66 isillustrated in an operating position with the brush block 2| when such ablock is at the position C .to be operated on by the drill 26. The camsurface 69 is formed near the top of the holder 2|, as viewed in Fig. 4,and to the outside thereof. This surface 69 is parallel with a linearpath on the brush block 20 corresponding to the row 25 to be formed, asis clearly shown in Fig. 3. The follower portion 15 of the stationarymeans 66 for engaging the cam surface 69 is adjustable in a directionradially of the table 22 and located in a vertical plane which alsoincludes the operating portion or drill H of the drill unit 26 (Fig. 5).successively moved from one-operating position to a next operatingposition relative to the drill II, the row'25 follows a linear pathbelow the drill H by virtue of the holder end 64 being pivotally movableto always ride against the follower portion 15 so that the distancebetween the point of engagement of the follower portion 15 with the camsurface 69 and the drill ii is always equal. The drilling of each holein the row 25, therefore, takes place in a path on the block 20 parallelto the cam surface 69, At the position D (Fig. 1) where the tuft isanchored in the holes in the row 25 there is a second stationary means68 for engaging the cam surface 69 to position the row 25 for lineartravel'beneath the tuft and anchor inserting unit 21.

In the drilling and tufting of the second row 30, which is inclinedrelative to the row 25, there is formed at the end 64 of the brushholder 2| and below the cam surface 69 a second cam surface 12 (Figs. 1,2, and 4) the surface of which is parallel to the row 3|]. The camsurface 72 is associated with a stationary means 13, similar inconstruction to the stationary means 68, which operates in all respectsrelative to the cam 12 similar to the operation of the stationary means68 and cam 69. A further description of the stationary means 13 and cam12 is, therefore, believed to be unnecessary.

In the movement of a block holder 2| from one operating position to anext related operating unit, the end 64 of the brush block is moved by acorresponding spring 65 to an outer position defined by the engagementof the pin 66 with the end 60 of the slot 61 (Figs. 2 and 3). On theholder 2| reaching an operating position the engagement of a stationarymeans with a corresponding cam surface moves the holder end 64 inwardlyagainst As the block 20 is amazes the spring 85, so that the spring 88,at each operating position, acts to positively maintain the engagementbetween a stationary means .and a corresponding cam surface. Althoughthe adjustment of the block 2| has been described above with respect tothe forming of two straight rows 25 and 38 which are inclined relativeto each other, it is apparent that straight rows 25 and 38 inclinedreversely'relative to each other as compared to their inclination inFigs. 2 and 3, or straight rows parallel to each other may be readilyformed by merely changing the slope of the cam surfaces on the holder 2|to conform to the desired row arrangement. Although during theadjustment of a brush holder 2| by a stationary means 88 or 13 movementthereof takes place relative to the locking bar 38, the block 28 isalways retained fixed relative to the holder by virtue of the slidingand pivotal movement of the locking rod 38 provided by its pivotedconnection with the table 22, and the action of the spring 48 to alwaysretain the locking rod 39 in frictional engagement with the block 28. Asimple means is thus provided for forming straight rows of bristlm in abrush block which is carried on a continuously rotatable table torelated operating units to complete the brush.

The drill units 26 and 83 are of a like construction and of a usualtype, with each drill unit being associated with a suitable drivingmechanism (not shown) operable to lower and raise a drill at the propertimes relative to the movement of the brush block thereunder. A furtherdescription of the drill is, therefore, thought to be unnecessary. Thetuft and anchor inserting units 21 and 34 are also of a likeconstruction. Only one unit 21 will, therefore, be referred to in detailin the following description.

As previousl mentioned, considerable difiiculty has been encountered inthe prior art brush mak ing machines using an anchor of straight formfor retaining a corresponding bristle tuft in a brush block, inproviding for the positive insertion of the anchor lengthwise into thebrush block. This difiiculty has been completely eliminated in thepresent invention by a combination anchor forming and carrying means 32adapted for coperative action with the jaw means 29 of the unit 21 toalways position the anchor within the jaw means to assure its beingproperly driven into a brush block by an anchor driving rod |35. Ananchor I4 for securing a tuft 16 within the brush block 28 is shown inFigs. 7 and 8. This anchor is essentially a, short, straight length of athin piece of hard wire which, although shown as round, may be of anyother configuration. The wire 11 (Fig. 6) from which the anchors 14 areformed is fed into the machine from a suitable supply source (not shown)over timed feeding rollers I8 and 19 into a stationary die member 8|having a wire receiving aperture therein. The

' wire 11 is guided in its passage from the supply 8 4, as viewedin'Flg. 6, having a notch for receiving the wire Tl from the block 8|.

The fingers 83 and 84 are pivotally supported intermediate their ends oncorresponding axis means 88 supported on a mounting plate 81 and areheld against the mounting plate by a retaining plate 88. The end 88 01'the finger 83 is con nected to one end of a tension spring 9|, theopposite end of which is connected to the mounting plate 81. The springacts to rotate the finger 83 in a clockwise direction, as viewed in Fig.6, and into engagement with the finger 84 to in turn rotate such fingerin a clockwise direction-and against a stop member 82 on the mountingplate -8'l. By virtue of this stop the fingers 83 and 84 are retained ina closed position by the spring 9|. The mounting plate 81 is carried ona floating or pivotally movable portion 33 rotatably supported in a bossportion 84 formed at the lower end of a long upright pivoted arm88'which is pivoted to a portion 81 of the machine frame on a shaft 88.The pivotal movement of the mounting plate 81 in one direction islimited by a stop member I88 fixed on the boss portion 94 and in anopposit direction by the engagement of the plate 81 directly with theportion. The mounting plate 81 is yieldably retained against the stopportion I88 by a spring 83 arranged in compression between the bossportion 84 and the retaining plate 81. When the closing ends of thefingers 83 and 84 are adjacent the stationary block 8|, the action ofthe spring 9! acts to retain these finger portions in sliding engagementagainst the block 8|. In other words, the stop I88 limits the pivotalmovement of the retaining plate 81 in a direction toward the die 8| whenthe fingers 83 and 84 are removed from the die 8|.

As previously noted, the pivotal movement of the fingers 83 and 84 in aclockwise direction, as viewed in Fig. 6, by the spring 8| is limited bythe stop 92. However, the fingers are capable of pivotal movementtogether in an opposite or counterclockwise direction on pressingupwardly of the finger .84 against thefinger 83. Thus in the forming ofan anchor 14 from the wire TI, with the wire extended between thefingers 83 and 84, a driving arm IN is moved upwardly against the finger84 to move the fingers 83 and 84 in a counterclockwise direction orupwardly relative to the die member 8|. This movement of the fingersprovides a cutting action between the finger 84 and the die member 8| tocut the wire 11 and leave an anchor 14 between the fingers 83 and 84.The length of the anchor 14 is determined by the timed movement of therollers 18 and 19. In other words, a partial relative rotation betweenthe rollers 18 and 19 moves the wire 71 a predetermined distance throughthe 'die 8| for cutting into an anchor. Thereafter the fingers 88 and 84move to the wire for cutting the wire and provide the anchor 14. Inaccomplishing this rotation of the rollers 18 and 13 the roller 18 ismounted on a shaft I82 which also carries a ratchet wheel I83. Theratchet |83 is associated with a pawl |84 pivoted on an arm I88 which isrotatably supported at one end on the shaft I82 and is pivotallyconnected at its oppositeend to a crank I81 eccentrlcally mounted on adriving shaft 88. Thus when the shaft |88 is rotated through a completerevolution the roller 18 is rotated through a predetermined angulardistance corresponding to the desired length of the anchor 14. Theroller 18 is essentially an idler roller carried at one end of a pivotedarmi'88, the opposite end of which is underthe tension of a spring I tocontinuously urge the roller 13 against the roller 18. The wire 11 isthus frictionally engaged between the rollers "and 19, with the positivemoving of the wire 11 between the rollers being facilitated by knurlingthe periph-- eral surface ofthe roller 18.

a stationary jaw I28.

11 The driving arm III forms one arm of a bell crank I I2 whichisplvotedat H3. The free 'end of the other arm II4 of the bell crank II2 has acam dollower III associated with a cam II'8 mounted on the driving shaftI88. The cam fol- ,lower is maintained in a following relation with thecam III by a spring I I1 connected to the arm IM and to a portion of themachine frame. It is seen, therefore, that the driving arm IIII isdriven against the finger 84 by the cam H8 and is returned to a rest oridle position out of engagement with the finger'84 by the spring II1.

By virtue of the closed ends of the fingers 83 and 84 being slidableagainst the stationary guiding block 8| during an anchor cuttingoperation and the cutting of the anchor 14 by the finger 94 the formedanchor 14 within the fingers 83 and 84 has one end II8 terminating atthe side surface of the fingers adjacent the block 8i. and an oppositeend I41 extended outwardly from the fingers (Fig. 7). The moving of thefingers 93 and 84 away from the stationary block 8i and to a positionfor presenting the anchor 14 to the jaw means 29 is accomplished bymeans including a roller II9 rotatably mounted on a shaft I29 carried inthe boss portion 94 of the pivoted arm 88. The roller I I9 isoperatively associated with a cam I2I mounted on the drive shaft I88 andis held in a following relation with the cam I2I by spring members I22arranged in compression between the pivoted arm 98 and the machine frameportion 81. The pivotal movement of the arm 99 by the springs I22 islimited by an adjustable stop I25 on the frame 91 to retain the followerH9 away from the cam I2I during the feeding and cutting operations ofthe wire 11. On completion of these operations the follower H9 is actedon by the high surface of the cam Hi to move the fingers 83 and with theanchor 14 therebetween toward the jaw means 29 and to the positionindicated in Fig. '1.

The jaw means 28 includes a block member I23 (Figs. 8 and9) which isslidably supported for movement in a vertical direction in cooperatingway members I24 and I28 mounted on the machine frame and carries amovable jaw I21 and The jaw I28 is fixed on the reciprocating block I23and is adapted for closing engagement with the movable jaw I21 which ispivotally supported on the sliding block I23 at I29. The jaw members I21and I28 are retained on the sliding block I23 by straps I3I and I32 withthe pivotal movement of the jaw I21 being guided and defined by thereception of a pin I33 carried on the block I23 in a slot I34 in the jawI21. Pivotal movement of the jaw I21 into a closing position with thejaw I28 is accomplished by a spring I38 acting at the upper end of thejaw I21, -as viewed in Figs. 7 and 8. which spring releasablyretains thejaws in such closing position. In closing position the closing portionsof the, jaws I21 and I28 have their inner faces in substantial parallelalignment. Each inner jaw face has a corresponding longitudinal grooveI31 and I38 for guidably retaining the ends of the anchor 14. Since themovable jaw I21 is spread away from the jaw I28, as is shown in Fig. '1,to receive the anchor 14 therebetween the inner surface of the closingportion of the jaw I28 is always in a substantially vertical plane.

The jaws I21 and I29 are normally spaced apart to receive therebetween adriver I 39 for the anchor 14. The driver I39 is formed as a part of theanchor driving means 29 which further includes a block I for carryingthe driver I28 12 slidable in the ways I24 and I28 but movable relativeto the block I23 (Fig. 9). The driver I39 Derated through a connectingrod I42 pivoted to the block I, while the jaws I21 and I28 are operatedthrough a corresponding connecting rod I43 pivoted to the block I23, therods I42 and I43 being actuated through suitable m hanism (not shown) toaccomplish a predetermined rielative movement between the driver I39 andthe jaws I21 and I23 during a tuft and anchor inserting operation. Inthe operation of the driver I39 its lower end I48 engages the uppersurface of the anchor 14, the ends of which are guidably retained orsupported in the grooves I38 and I39 of the jaws I21 and I28,respectively. In one embodiment of the invention the anchor 14 has adiameter of about .018 inches and is about V; of an inch long. Becauseof the small diameter of the anchor the driver I39 has a correspondingthickness of about .018 inch and a width of about 54; of an inch so asto be of a narrow, thin, ribbon form. To assure a positive engagement ofthe driver with the anchor at all times of operation, the stationary jawI29 above the closing portion thereof is integrally formed with aprojecting or guide portion I44 (Fig. 8) extended toward the movable jawI 21 which is formed with a corresponding shoulder portion I46 toguidably receive the projection I44 when the jaws are in a closingposition. The projection is formed with slots or grooves for slidablyreceiving the driver I39. with the vertical movement of the driver beingsuch that it is continuously guided in a vertical path within theprojection I44. The groove I31 in the closing portion of the jaw I28 iscontinuous with one of the guiding grooves in the projection I44 so thatthe driver is continuously-guided relative to the jaw I28, and alignedfor reception in the groove I38 in the movable jaw I21 when the jaws arein a closing position. The driver is thus always capable of engaging theanchor 14 so that any possibility of the driver not riding in thegrooves I31 and I38 during an anchor inserting operation, as sometimesoccurs when the driver is retracted from the jaws at some point in itsmovement, is positively eliminated.

To assure the anchor 14 always being driven lengthwise into a brushblock 28 it is necessary that, prior to the anchor driving operation, itbe positioned lengthwise between the jaws I21 and I 28 in a planesubstantially normal to the inner faces of the jaw closingportions, orto the grooves l31and I38 in such faces. with the ends of the anchor incorresponding grooves. Where the anchor is between the jaws in a, tiltedor inclined position relative to this plane, the driver I39, even thoughengageabie with the upper side of the anchor, acts to further tilt theanchor rather than to properly straighten or position it for insertionlengthwise into the block 28. As a result of this action the anchoroftentimes is inserted endwise into the block so that it fails entirelyto secure'a corresponding tuft in the 13 the inner face of the closingportionof the stationary Jaw I28 when the jaws are in their openposition as shown in Fig. 7. The ends of the fingers 88 and 84 aretapered to facilitate the fingers being inserted between the Jaws I21and I28 and by virtue of the pivotal movement of the retaining plate 81relative to the pivot arm 98 the fingers 88 and 84 are slidably movedagainst the stationary jaw I28 to a position at which the anchor end H8is directly opposite the groove I 31 in the stationary Jaw I28. Thisposition of the anchor end H8 is determined by the movement of thefingers 88 and 84 by the cam I2I. Further the jaws I21 and I28 arearranged in a plane substantially normal to the plane of pivotalmovement of the fingers 88 and 84 so that the anchor 14 is positioned ina plane substantially normal to the plane of the inner faces of theclosing portions of the laws I 21 and I28 concurrently with the locationof the anchor end II8 immediately at the groove I81. The end I41 of theanchor 14 is thus in turn located opposite the groove I88 in the movablejaw I21. With the anchor 14 retained in this position by the fingers 83and 84 the movable jaw I21 is moved into a closing position with thestationary Jaw I28 to receive the anchor 14 for guidable support withinthe corresponding grooves I81 and I38, as is shown in Fig. 8, whileextended lengthwise between the jaws is a plane substantially normal tothe inner faces of the jaw closing portions. After the jaws I21 and I28have been closed on the anchor 14 the fingers 88 and 84 are moved out ofan anchor holding or carrying position by the cam I2I, the end of thefingers 88 and 84 being Pulled away from the anchor 14 by the anchorspreading the flngem apart against the action of the spring 9|.

Since any vertical movement of the jaw means 29 and in turn of the jawsI21 and I28 during the time the anchor 14 is not held by the fingers 88and 84 might result in tilting the anchor between the .Iaws, the jawmeans is held against any vertical movement until after the jaws haveclosed on the anchor. Movement of the jaw I21, while the jaw means isstationary is made by a cam portion I48 carried on a shaft I49 rotatablysupported in a portion I5I of the machine frame including the ways I24and I28. The cam I48 (Figs. 8 and 9) is suitably keyed to the shaft I49which also carries thereon in a keyed relation an arm I52 pivotallyconnected with a connecting rod I58 having a follower I54 at its freeend for engaging a cam I58 mounted on a driven shaft I51 which is alsocommon to the picker mechanism of the machine, and which will be laterdescribed. The cam I48 is engageable with a corresponding projection I58at the top of the movable jaw I21, as viewed in Figs. 8 and 9, and isoperated by the cam I58 and the follower I54 to move the jaw I21relative to the jaw I28 in a predetermined sequence relative to themoving of the fingers 83 and 84 by the cam I 2| In the picker mechanismshown in Fig. 9, the bristles I59 used in making the brushes are storedin a magazine or rack I8I arranged in a substantially upright orvertical position, the bristles being positioned in a longitudinaldirection and extending from front to back as viewed in Fig. 9. Aweighted plate I82 on the top of the bristles in the rack I8I maintainsa certain amount of pressure on the bristles to feed them through therack and toward the pivoted picker member 3|.

The picker member 8| has a substantially arcu- 14' ate portion I88 whichis pivotally movable across the lower end of the bristle magazine, asviewed in Fig. 9, and has a radial arm I84 carried on a rotatable shaftI 88. The outer peripheral edge of the arcuate portion I88 maintains thebristles I59 in the rack I H as the picker member'is rotated acrossthelower end thereof. This peripheral edg has a notch I 81 which is of asize to remove from the face of the bristles at the lower end of thestorage rack I8I a quantity of bristles in an amount to produce a tuft18 of a desired size for the brush. The picker member 8I is shown inFig. 9 at one end of its operating stroke with a tuft 18 in the notchI81 at a position to be received between the jaws I21 and I28 forinsertion with the anchor 14 into the brush block 28. The picker memberis pivotally movable in a plane which is substantially parallel andadiacent to the plane of vertical movement of the jaw means 29 to permitfree relative movement between these parts. The shoulder or ofisetportion I88 near one end of the arcuate portion I88 acts to pack downthe bristles in the storage rack.

It is important, of course, that thebristles at the lower end of themagazine I8I be in a condition such that a substantially uniformquantity of bristles is received within the notch I81 on each passagethereof across the magazine. Althoughthe upright position of themagazine in cooperation with the weighted plat I82 tends -to pack thebristles toward the lower end, this packing is usually inadequate,particularly when speeds. As previously mentioned, the shoulder portionI88 on the picker assists in this packing function. To further pack thebristles at the lower end of the magazine I8I there is provided a packermeans comprised of a packer arm I12 and an operating arm I13 fixed withrespect to each other and supported for pivotal movement on a stationaryaxis means I14. The lower end of the packer arm I12, as viewed in Fig.v9, is formed with two spaced projecting portions which on pivotalmovement of the arm I12 towards the magazine I8I acts to pack thebristles at the lower end of the magazine in a direction toward thepicker member 8|. The arm I12 is driven by means-including a .connectingrod I18 connected at one end to the lower end of the arm I18 andpivotally connected at its opposite end to the leg I11 of a bell crankI18. The bell crank I 18 is pivotally supported at I19 'and has the legI 8I thereof pivoted to a sleeve member I82 slidable on a shank I88formed as part of an eccen trio I84 supported on the drive shaft I51.The eccentric I 84, sleeve I82, and bell crank I18 are all part of thedriving mechanism which provides a delayed or lost motion action forproperly timing the operation of-the pa cker arm I12 with reference tothe operation of the picker member 8|, so that the packer arm I12 ismoved toward the picker member 8I as the notch I 81 is moved in acounterclockwise direction, as viewed in Fig. 9 across the lower end ofthe bristle magazine I 8I.

A pivotal movement of the picker member 8| across the lower end of therack I8l is accomplished by suitable operating mechanism (not shown)associated with the shaft I88. In the operation of the picker member 3|the notch I 81, when moved in a counterclockwise direction, as viewed inFig. 9, across the lower end of the brietle rack I 8| cuts or removes ameasured quantity of bristles from the magazine. When the notch passesfrom the bristle magazine the bristles are carry the tuft from thebuffer plate to a position for engagement by the jaw means 28. Thiscarrying of the tuft 18 is accomplished by a tumbler unit In whichcooperates with the buffer plate I88 to retain the tuft 18 within thenotch I 81 at all times of its transfer from the bristle rack I8I to thjaw means 28.

The tumbler "I is located below the picker member 8| and above theholder 2I for a brush block 2|! (Fig. 9) and is mounted on a shaft I88for pivotal movement in and out of vertical alignment with the jaw means28. As shown in Fig. 9 the tumbler is in vertical alignment with the jawmeans 28 and in this position functions during an anchor and tuftinserting operation, to double up the bristle tuft 18 and to guide thedoubled tuft all the way down to a position in the brush block 28. Thetumbler "I is pivotally moved by a crank arm I81 rigidly mounted on thetumbler shaft I88 and pivotally connected at its free end to one end ofa connecting rod I88. The other end of the rod I88 is pivotallyconnected at I88 to the arm I11 of the bell crank I18. The drivingmechanism for the packer arm I12 is thus common to the driving mechanismfor the tumbler ill with the lost motion in this driving mechanism beingsuch as to properly time the movement of the tumbler with respect to thejaw means 28 and the picker member 8|. Thus as shown in Fig. 9, thetumbler I1I is in'vertical alignment with the jaw means 28 concurrentlywith the location of the tuft 18 at a position to be engaged by the jawsI21 and I28 of the jaw means 28.

With the tumbler I1I in vertical alignment with the jaw means 28. theupper edge thereof is used to retain the tuft 18 within the notch I81after the notch is moved away from the buffer I88. That is, the extremeend I 8I of the buffer member I88 stops short of the center of the jawmeans 28 so as not to interfere with the operation of the jaws I21 andI28 in engaging the tuft 18 and carrying the same to the brush block 28.flowever, because of the timed relation of the tumbler in relative tothe jaw means and picker member, the upper edge of the tumbler I1I is insubstantial alignment with the arcuate surface of the buffer member I88at the time the notch I81 passes oil the buffer I88 so that the tuft 18is continuously retained within the notch I81 for transfer from the rackI8I into the path of movement of the jaw means 28 and between the jawsI21 and I 28. Thus at the jaw means 28 the tuft 18 is retained in thenotch I81 by the upper surface of the tumbler I1I. It is seen,therefore, that the tumbler I1I performs its usual functions inretaining inserted bristle tufts free of the hole in which a new tuft isto be inserted, and a bristle doubled until the time it is inserted inthe brush block 28, and further acts to retain the tuft 18 within thepicker member 8| until it is engaged by the jaw means 28.

From the above description it is seen that both the anchor 14 andbristle tuft 18 are presented to the jaws I21 and I28 for insertiontogether into 16 the brush block 28 by the driver I88. In Order for thejaws I21 and I28 to close on both the anchor and the tuft it isnecessary that they be in their open-position, shown in Figs. 7 and 9,when the anchor and tuft are first presented therebetween. In theembodiment of the invention above referred to, the overall verticalmovement of the jaw means 28 above the position shown in Figs. '7 and 9,at which the tuft is received between the jaws I21 and I28, is onlyabout one quarter of an inch. In this one quarter inch overall movementthe jaws I21 and I28 may be spread apart by the cam I48 acting on themovable jaw I21 either on the up-stroke of the jaws away from the tuftreceiving position shown in Figs. 7 and 9, or on the down stroke of thejaws from a top or uppermost position toward a tuft-receiving position,or over both the up and down strokes of the jaws in the one quarter inchoverall movement. The jaw carrying fingers 88 and 84 are operated tomove between the jaws I21 and I28 after they are in an open position andinto sliding engagement with the inner surface of the closing portion onthe stationary jaw I28. This relative positicn of the anchor carryingfingers and the jaws I21 and I28 is retained until the laws are moved totheir position shown in Figs. 7 and 9 for receiving the bristle tuft 18.

At this position of the jaws I21 and I28 the jaw means 28 is retainedagainst vertical movement and the cam I48 is moved out of an engagingposition with the projection I58 to permit the jaw I21 to close with thejaw I28, on both the anchor 14 and the bristle tuft 18. After the jawI21 has closed .with the stationary jaw I28 the anchor holding fingers83 and 84 are withdrawn from between the jaws and the jaw means 28 moveddownwardly into the tumbler I1I concurrently with the operation of thedriver I88 to insert the tuft 18 and anchor 14 in the brush block 28. Itis seen, therefore, that the jaws I21 and I28 are retained against anyvertical movement downwardly, while the jaw I21 is being closed on theanchor 14 and tuft 18, and that their downward movement is continuedsubstantially concurrently with the retraction of the fingers 88 and 84from the anchor 14. As a result the guiding of the fingers 83 and '84 onthe inner face of the stationary jaw I28 to properly locate the anchor14 for gripping between the Jaws I21 and I28 is positively retained byvirtue of the anchor 14 be ins stationary relative to the law I28 duringthe closing of the jaws.

From a consideration of the above description and drawings it is seenthatthe invention provides a machine in which a brush block carried on acontinuously rotating table to related operating units is automaticallyadjusted during the rotation of the table such that the completed brushis formed with straight rows of bristles. The in vention furtherprovides means for assuring an anchor of straight form being drivenlengthwise into the brush block to positively secure a correspondingbristle tuft. Although the machine has been particularly described withrespect to making a brush in one continuous operation having a pair ofstraight rows thereon inclined relative to each other it is apparentthat the means fOr adlusting the brush block holder 2I are adapted toprovide, in conjunction with the brush holder, a row of bristles on thebrush of any form. In those instances where the brush block is formed bya molding operation, during which operation the holes for receiving thebristles are simultaneously formed, the drills 28 and 33 may beeliminated acsaum l7 and one or more anchor and tuft inserting unitsused depending upon the number of rows of holes in the molded handle tobe tufted.

Although the invention has been described with reference to a specificembodiment thereof it is to be understood that it is not to be solimited since modifications and changes can be made therein within theintended scope of this invention as defined by the appended claims.
